On Friday (October 5th, 2012) Katherine attended Variety's Fourth Annual Power Of Women Luncheon held at the Beverly Wilshire Hotel, where she was honored by the American Cancer society with the Celebrating More Birthdays Award. The award was given for her work in helping to amplify the awareness of cancer related issues through her public support of her mother's cancer experience.

Speaking to the press on the red carpet Katherine explained that she felt it should be her mother accepting the award as both a role model and a cancer survivor instead of her. She also stressed the importance of regular screening and early detection in helping to save lives.
